Spotify, Google, Pandora and Amazon have teamed up to appeal a controversial ruling by the U.S. Copyright Royalty Board that, if it goes through, would increase payouts to songwriters by 44%, Variety has learned.

Note one big name missing from that list. Apple.

Sources say that Apple Music is alone among the major streaming services in not planning to appeal — as confirmed by songwriters’ orgs rushing to heap praise on Apple while condemning the seemingly unified front of the other digital companies.

And:

Bart Herbison, executive director of the Nashville Songwriters Association International: “It is unfortunate that Amazon and Spotify decided to file an appeal on the CRB’s decision to pay American songwriters higher digital mechanical royalties,” he said in a statement. “Many songwriters have found it difficult to stay in the profession in the era of streaming music. You cannot feed a family when you earn hundreds of dollars for millions of streams.”

And:

Israelite did single out Apple for praise for not participating in an appeal. “We thank Apple Music for accepting the CRB decision and continuing to be a friend to songwriters,” he said. “While Spotify and Amazon surely hope this will play out in a quiet appellate courtroom, every songwriter and every fan of music should stand up and take notice.
